Scaling Virtual Environments
Virtualization is the fastest growing environment in nearly every data center today. Gartner forecasts that server virtualization will grow from 75.2% in 2012 to 82.4% in 2015. Although the benefits of virtualization are indisputable, several challenges must be addressed to ensure the success of any virtualization initiative.
Virtualized environments are very dynamic by nature. To accommodate rapid growth and fluctuations in demand, the infrastructure needs to support easy scaling of individual VMs, as well as the addition of new virtualized workloads. Today’s virtualization solutions were designed for easy scaling of compute, simply by adding virtualization hosts using a ‘building block’ approach. Network scaling is becoming more simplified with software-defined network architectures. Unfortunately, scaling storage continues to be one of the top challenges for increasing the level of virtualization in the modern datacenter.
By using a ‘one size fits all’ approach, traditional storage frequently becomes the bottleneck when scaling virtualized environments. Let’s take a moment to review some of the challenges enterprises face when using general-purpose storage solutions for virtualization.
